ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 751,138, dated February2, 1904.

, Application filed February 9, 1903. Serial No. 142,566. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM G. AVERY, a citizen of the United States,residing at Painesville, in the county of Lake and State of Ohio, haveinvented certain new and usefulImprovements in Elevator-Buckets; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to buekets, more especially such as are designedfor excavating, elevating, loading, unloading, or transporting material.

The objects of my invention are to first obtain a bucket which isstronger and more cheaply constructed than the so called struck-up orpressed bucket and more uniform when finished.

My invention consists in forming the bucket of three blanks, one blankforming the main body portion of the bucket and two blanks forming theends, the whole being put together in the manner hereinafter described,and fully set forth in the claims.

In the drawings, Figure I represents in plan a blank from which the bodyof the bucket can be formed. Fig. II illustrates the blank illustratedin Fig. I approximately shaped.

Fig. III illustrates a blank which I prefer to employ for the endpieces. Fig. IV illustrates a manner in which the blank illustrated inFig. III may be secured in place. Fig. V illustrates a finished bucket.

In the drawings and in the following description I have illustrated andwill describe my preferred method of constructing a bucket.

A represents a blank which forms the body of the bucket. This blank A isprovided with flange-pieces a, a, a and a and is preferably cut away atthe corners, forming shoulders, as at b o 6 Z). The blank A is suitablyshaped, as illustrated in Fig. II, and the flanges a, a, a and a turnedinward. These flanges a, a, a and a are preferably perforated for thereception of suitable rivets before being bent into shape; but, ifdesired, this perforation may be a subsequent operation.

The side pieces B are formed of a blank such as is illustrated in Fig.111. The upper portion 0 being shaped in such contour as to fit tightlyor snugly within the body inside of the flanges a a or a a and the lowerportion B is made to conform to the outer contour of the body A' of thebucket at its side. Also at the extreme lower end of the blank B, I forma portion E, which is bent at right angles to the blank in such a manneras to embrace the bottom portion of the body A.

When the side pieces B are bent to the shape illustrated by the solidand dotted lines, they will inclose the flanges a a or a a between them,and the parts are then riveted or secured in other suitable manner. Theflange E is also riveted or secured to the bottom of the bucket, asillustrated in Figs. IV and V, and thus the bucket is complete, uniform,and strongand can be made more economical on account of the fact thatthe body portion A, which receives the main port-ion of the wear, can bemade of heavier gage metal than the side portions, and as the rivets onthe interior of the bucket (when rivets are used) are struck flush tothe metal the interior of the bucket is smooth and prevents or lessensthe liability of packing of the material.

Instead of making the blank B as illustrated in Figs. III and IV, sothat a double thickness of wall is attained, I can form it of such shapeas is illustrated from the lines as w downward, including the portions Dand E; but I prefer "to construct it as illustrated and described.

What I claim is 1. A bucket of the type set forth comprising a bodyportion, having inwardly-projecting flanges, at its ends, andoppositely-disposed side pieces adapted to engage said flanges, saidside pieces being provided with a flange adapted to engage the bottomportion of the body.

2. In a bucket of the type set forth, a body portion, formed of anintegral blank having opposite inwardly-projecting flanges at both endssaid flanges extending from the upper portion of, the body to a pointnear the bottom thereof leaving aportion of the body without hoga andState of Ohio, this 30th day of J anuary, 1903.
